The purpose of life is to experience fully the condition of a real living being, so as to be able to have mercy the day we will encounter some little being, experiencing himself the same problem we have already encounter.
There is surely many levels of reality for a living being and we dont need to experience all the problems of life, but we will at least have to experience one problem (or there is no use to live).
There is NO purpose to LIFE, it just occurred. No grand plan, no goal to achieve
It (LIFE) cane into being because physics allows certain chemical reactions to occur. These chemical reactions have the ability to become self sustaining
Self sustaining chemicals have the ability to morph into self replicating entities
Self replicating entities have the ability to become aware they self replicating entities and tend to carry on the process of producing more self replicating entities because the process has become a form of pleasure
None of the above is in any way shape or form devine or miraculous. Cannot even be said unlikely to occur, since it did / has occured
So no god(s) required, no grand plan, no goal to achieve. You, yes all of yous, are here at the end of accumulated occurrences
The sum of those accumulated occurrences will propel you through YOUR life happenings. Some of the situations yous will encounter yous might have control over
But yous frequently will encounter the nagging doubt "if only"
Welcome to reality
